响应面法优化白墨在镭射卡纸上的附着力性能

目的为了优化UV白墨在烟包用镭射卡纸上的附着力,运用响应面实验设计方法对印刷工艺进行优化。方法以在曼罗兰印刷机上生产红双喜烟标为例,以UV灯功率、印刷车速为自变量,以白墨在镭射卡纸上的附着力为因变量,利用Design Expert软件,设计响应面图表,对2个自变量进行多次拟合,建立相应的三维曲面,得到最优的数学模型,最后得到最优的印刷工艺,并加以实验验证。结果当UV灯功率密度为120 W/cm,印刷机的印刷速度为8580张/h,能够使得白墨在镭射卡纸上有最优的附着力。结论把响应面实验设计方法来优化烟包印刷工艺,在减少实验次数的同时,对白墨在镭射卡纸上的附着力具有较好的预测效果。

Optimization of Adhesion Performance of White Ink on Laser Paper in Response Surface Method

The work aims to improve the adhesion of white UV ink on laser paper with regard to cigarette package and optimize the printing process with the experimental design method for response surface. By taking Double Happiness cigarette label produced with Manroland printing machine as an example, and with the power of UV lamp and the speed of printing machine as the independent variables, and the adhesion of white ink on the laser paper as the dependent variable, the Design Expert software was used to design response surface chart. Multiplex fitting of the two independent variables was conducted to establish the corresponding 3D curve surface and obtain the optimal mathematical model, so as to finally obtain the optimal printing process and have such process verified through experiment. When the power of UV lamp was 120 w/cm, the speed of printing machine was 8,580 sheets/h, the optimal adhesion of white ink on laser paper could be obtained. The experimental design method for response surface used to optimize the printing process of cigarette packages can properly predict the adhesion of white ink on the laser paper at the time of reducing the number of experiments.
